Abstract
A mechanical, non-fluid-power clutch is disclosed. Inside a clutch housing, a cup element is fixed to a first shaft. First splined discs radiate inwardly from the cup. A second shaft, coaxial with the first shaft, has a second set of splined discs which radiate outwardly in an interleaved arrangement with the first discs, so as to form a disc stack. A collar cam is also carried by the cup element. This collar cam has a fixed element, and a movable element which can squeeze the disc stack and consequently couple the shafts. Interconnector balls move radially outwardly between the collar cam elements to effect the collar cam element movement and shaft coupling. The radially outward movement of the balls is caused by a sleeve cam telescoped upon the second shaft. The sleeve cam can be moved axially by a yoke arrangement, which is controlled by a lever located outside the housing.
